CATALYTIC REACTOR INCLUDING ONE CELLULAR AREA HAVING CONTROLLED MACROPOROSITY AND A CONTROLLED MICROSTRUCTURE AND ONE AREA HAVING A STANDARD MICROSTRUCTURE
CATALYTIC REACTOR INCLUDING ONE CELLULAR AREA HAVING CONTROLLED MACROPOROSITY AND A CONTROLLED MICROSTRUCTURE AND ONE AREA HAVING A STANDARD MICROSTRUCTURE
The invention relates to a catalytic reactor including: at least one first architecture/microstructure (1) including a ceramic and/or metal cellular architecture having a pore size of 2 to 80 ppi and a macroporosity of more than 85%, and a microstructure having a grain size of 100 nm to 5 microns, and skeleton densification of more than 95%, and a catalytic layer; and at least one second architecture/microstructure (2) including a spherical or cylindrical architecture having a pore size of 0.1 to 100 μm and a macroporosity of less than 60%, and a microstructure having a grain size of 20 nm to 10 μm and a skeleton densification of 20% to 90%, and a catalytic layer; the first and second architecture/microstructure being stacked inside said reactor.
